COMBINED CI-IURN AND BUTTER-WORKER.

To all whom it may concern:

Be it known that I, REUBEN B. DISBROW, a citizen of the United States,residing at Owatonna, in the county of Steele and State of Minnesota,have invented certain new and useful Improvements in Combined Churns andButter-lVorkers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to combined churn and butter workers, and has forits object to improve the same in the several particulars hereinafterdescribed and defined in the claims.

In the combined churn and butter workers of the type wherein cooperatingbutter working rollers are placed within an ap proximately horizontalrotary drum, and wherein the butter is lifted by a shelf or flights anddelivered between the working rollers, there is a tendency on the risingside of the drum, for the mass of butter, because of its frictionalcontact with the heads of the drum, to fall backward at the centralportion of the drum, and this has a tendency to keep the butteraccumulated ator shifted toward the heads of the drum. In my presentinvention, I avoid this by the use of one or more so-called dividerslocated approxi mately at the longitudinal center of the drum, andpreferably extended in a plane that intersects the axis of the drum at aright angle and projects inward from the shell of the drum toward one ofthe working rollers. This divider acts as a sort of an equalizer toprevent the butter from working toward the heads of the drum and keepsthe same evenly distributed longitudinally of the drum.

In the accompanying drawings which illustrate the invention, likecharacters in dicate like parts throughout the several views.-

Referring to the drawings, Figure 1 is a transverse vertical sectiontaken through the intermediate portion of the combined churn and butterworker, embodying my invention; Fig. 2 is a longitudinal section takenthrough the drum on the line 00 m of Fig. 1; and Fig. 3 is a fragmentaryview showing a portion of the drum and the socalled divider blade,looking at the inner edge of the latter.

Specification of Letters Patent.

Application filed September 21, 1911.

Patented Feb. 20, 1912. Serial No. 650,578.

The drum 1, which is of the usual or any suitable construction, may bejournaled to frame pedestals 2, in the usual or in any suitable way.Said drum is preferably provided with the customary peripheral door '3,with an internal lifting shelf 4 and with several internal flights 5.

The numerals 6 and 7 indicate the cooperating working rollers which arelocated Within the drum, extended parallel to the axis thereof, from onedrum head to the other, and are suitably journaled in the drum heads.These working rollers and the drum are adapted to be ,rotated in thedirec tion of the arrows marked in Fig. 1, by the usual well known, orin any suitable driv-' ing mechanism, not necessary for .the purposes ofthis case to consider.

The socalled divider blade or equalizer 8 is preferably, but notnecessarily, made of wood and is rigidly secured to the inner surface ofthe drum shell by angle strips 9. The inner and forward edges of thisblade 8 are preferably beveled and made quite sharp, as shown in thedrawings. The beveled inner edge of the said blade 8 terminates quiteclose to the roller 7, and the said blade is located preferably about 90degrees ahead of the lifting shelf 4, the term head here used,'being inrespect to the direction of the rotation of the drum.

One of the flights 5 is preferably alined longitudinally of the drum,with the intermediate portion of the divider blade 8, and this flight iscut in two at its central portion, and preferably beveled, as indicatedat 5 in Fig. 2.

In the butter working action and under rotation of the drum in thedirection of the arrow marked on Fig. 1, the butter, after being workedbetween the rollers, will, on the rising side of the drum, be engaged bythe divider or equalizer blade 8, and the latter will cut its waythrough the central portion of the body of the butter, thus dividing thesame, but at the same time increasing the frictional engagement with thecentral portion of the body of the butter, so that it will not fallbackward at the central portion of the drum faster than it does at theends of the drum. Thus the body of the butter is raised to the rollersevenly, or approxi mately so, at all points longitudinally of the drum.The dividing flight 5, which is longitudinally alined with the dividerblade 8, also assists in accomplishing this result.

The divider blade, in addition to the important function above noted,also assists in the working of the butter and insures better mixing ofthe butter and salt.

The improved device adds practically nothing to the cost of the machineand very greatly improves the action thereof. These statements are basedon actual manufacture and use of a large number of machines embodyingthe improvement.

l/Vhat I claim is:

1. In a machine of the kind described, the combination with anapproximately horizontal rotary drum having internal working rollers, ofa divider projecting inward from the intermediate portion of the shellof the drum.

2. In a machine of the kind described, the combination with anapproximately horizontal rotary drum having cooperating working rollersand lifting shelf within'the same, of a divider projecting inward fromthe intermediate portion of the shell of the drum toward one of the saidrollers.

3. In a machine of the kind described, the combination with anapproximately horizontal rotary drum having an internal lifting shelfand cooperating working rollers within said drum, of a dividerprojecting inward of the intermediate portion of the shell of the drum,the said lifting shelf being terminated adjacent to one of the saidrollers and the said divider being terminated adjacent to the other ofthe said rollers.

4. In a machine of the kind described, the combination with anapproximately horizontal rotary drum having an internal working roller,of a divider blade projecting inward from the intermediate portion ofthe shell of the drum and located in a plane that transverselyintersects the axis of the drum.

5. In a machine of the kind described, the combination with anapproximately horizontal rotary drum having cooperating working rollersand lifting shelf within the same, of a divider blade projecting inwardfrom the intermediate portion of the shell. of the drum toward one ofsaid rollers, and located in a plane that intersects the axis of thedrum approximately at a right angle.

6. In a machine of the kind described, the combination with anapproximately horizontal rotary drum having internal lifting shelf andcooperating working rollers, of a divider blade projecting inward fromthe central portion of the shell of the drum, located in a plane thatintersects the axis of the drum, approximately at a right angle, thesaid lifting shelf being terminated adjacent to one of the said rollersand the divider blade being terminated adjacent to the other of saidrollers.

7. In a machine of the kind described, the combination with anapproximately horizontal rotary drum having internal lifting shelf andcooperating working rollers, of: a divider blade projecting inward fromthe central portion of the shell of the drum located in a plane thatintersects the axis of the drum, approximately at a right angle, thesaid lifting shelf being terminated adjacent to one of the said rollersand the divider blade being terminated adjacent to the other of saidrollers, and a longitudinally divided flight projecting inward from theshell of the drum and longitudinally alined with the said dividerblade,'substantially as described.

In testimony whereof I atfix my signature in presence of two witnesses.
